Megure comes to the detective agency to implore Kogoro to help him. Kogoro accepts, and Megure explains the situation: a young man called Ryuji is suspected of having killed his uncle, a famous literature scholar. A witness claims to have seen him exit his uncle's house at the time of the crime.

Suspects:

Prank Caller

A suspected fire occurred and fire fighters were sent there to find there wasn't any fire.

As Inspector Megure is about to leave, Conan stops him telling that Kogoro told him he should ask if any fire trucks were dispatched in Yotsubadai and calls. Then, Kogoro gets out of the washroom and was told by Megure that a small fire occurred at 8 PM and before the detective could express his misunderstanding, Conan stuns him out and hides behind the couch ready to make Sleeping Kogoro's deduction start. After having knocked the elder off, he left her house with Hide. He first entered her home at seven and then headed towards Yotsubadai with her inside his van. He then murdered Reigan and started a fire in a nearby house's courtyard.

Arson (Past)

Location:

Yotsubadai District

Time:

3 weeks ago

Culprit:

Ryuji Maihama

The fire he had set in a home near Reigan's house.

He then called the fire department and also made a false report of a fire in Sasago-cho. Has he heard the fire trucks coming, he woke Hide up and turned on the TV of the car and asked her for the money's location before knocking her out again. He then moved her back to Sasago-cho and placed her in her original position and made it seem as if he was there the whole time all in order to make her believe she heard the siren and the TV in her home although she was in a car parked in front of Reigan's house. It would then confirm Maihama's alibi. The evidence is inside Hide's nose and ears. She smelled the fire but didn't hear the bathtub's notice programmed to be at 8.A thorough investigation of Maihama's car will confirm all. Megure then calls his subordinates to inform them of the facts. It was all clear now Ryuji Maihama was the culprit.

As Megure leaves the detective agency, he thanks Kogoro for his help. He then wakes up and starts inventing other conclusions about the alibi which makes Inspector Megure curious and Conan jumps on him trying to make him stop talking. He then tells himself it's the last time he'd call for Kogoro's help.
